This is one of the valid ways to compile U-Boot.

...and your "u-boot.bin" is configured for the "at91sam9263ek" target,
with  environment variables in SPI DATAFLASH CS0.

You can do this, but ...

Note that there are several configurations of U-Boot available for
this board (see Makefile):

...
2808 at91sam9263ek_norflash_config \
2809 at91sam9263ek_norflash_boot_config \
2810 at91sam9263ek_nandflash_config \
2811 at91sam9263ek_dataflash_config \
2812 at91sam9263ek_dataflash_cs0_config \
2813 at91sam9263ek_config    :       unconfig
...

You probably want to read the AT91SAM9263EK entry in the
documentation (file doc/README.at91).

Maybe there is no such option available for this board?
